in order to avoid misunderstandings, i list herebelow my actions:

i've used on paperino the kernel 2.6.27.2 patched with ilpo's
21.10.2008 patch (see please comment 47 in
http://bugzilla.kernel.org/show_bug.cgi?id=11721, and NOT with the patch
contained in comment 58, right?)
i've modified the following files:
echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
echo 0 > /proc/sys/net/ipv4/tcp_timestamps
echo 1 > /proc/sys/net/ipv4/tcp_sack

the results are that i CAN navigate (w3m kernel.org) and update my
system (apt-get update in debian).

should it be of any help to ilpo, i attach the usual tcpdump on the wan
eth of topolino (my home server/gw)

ciao!
aldo
